Let x be the number of days it takes for the two machines to have the same amount of ice cream left.
The vanilla machine has (180 - 20x) cups of ice cream left after x days, and the chocolate machine has (140 - 16x) cups left after x days.
The equation to solve for x is:
180 - 20x = 140 - 16x
Add 20x to both sides of the equation:
180 = 140 + 4x
Subtract 140 from both sides of the equation:
40 = 4x
Divide both sides by 4:
x = 10
It will take 10 days for the two machines to have the same amount of ice cream left.
An ice cream shop makes vanilla and chocolate ice cream. The vanilla ice cream machine has a 180-cup capacity, and it sells 20 cups per day. The chocolate ice cream machine has a 140-cup capacity, and it sells 16 cups per day. Write and solve an equation to show when the two machines will have the same amount of ice cream lef
